' Beit known that we, fand ERN'nsT E. HEINTZ, 1 citizens ofthe y vUnitedl States, residing aty Detroit, in the.

5 .county lof Wayne and State ofl Michigan,

have-invented certain new and useful Improvements in Door' Locks, of which ythe ollowing is a speciiication. l.

vThis invention relates-'to aj lock, and-,is

maniere particularly,*directedl to the dogging `mechanism -and the control thereof'.

Y The .object lisgto providea simple and positive actuating meansfor controlling the l dogging mechanism.l Afurther object is-to 15. provide means ywhereby the doggin trol ma be carried' by jastamping detacha ly secured to thelockcasing over the triniming. This enables'the manu- 'facturer to assemblethis control afterthe job has been completed andthe trimmingvsecured-in place. "One of th y ofthe present art is that they are relatively expensive tomanufacture and are not easily.

diseases with dfsg Controls assembledfin .thelock casing', 'In 'a prior yexpensive-to build and Iis lnot 'so easily assembled in the'casing. -Wefha've provided is yieldably forced intol either-the "oi or on position.

A coil springt is suit'- ably carried onv the spindle Eor' exerting a pressure Vfor holding the vertical spindle against the ears carried by. the sliding bolt parts.

" to preventv unnecessary rattle between the A yoke-shaped dog i is pivotally supl portedin the back-plate'y' as at k. A rollback m operated by' a handle outside of' the` car engages a projection n carried by a slide ingbolt so that when the outside handle of i i the car isturnedthe bolt-may b e retracted.

However, the rollLback isadditionally provided vwith a shoulder o, which is engaged by the dogging arm p whichfw'ill prevent *movement ot the roll-back when the dogisin the position as shown in'Fig. 1.' The other arm y of the dog designatedA p1 Yis engaged in Ithecup-shaped member xq 'actuated' by the tumbler-lock. On the insertion of a'key this dog may 'be actuated 'to release the roll-,back so that one `may retractthe bolt for opening tllijdooI-.- lThis much -of the construction is 0 r :Our improvement resides in providing the engages one end; of the snapover control later to be described.

A small coil spring fw is positioned about'the lever between thetail r and the back of the esoutcheon plate. kThe ,normal tendency of this spring is to eiipand, and consequently it forces the lever to. snap-over cenmay expand as far as possible.
